What iPad apps are you using?

My district is looking at ways to integrate iPads into classroom instruction (like everyone else!) and I would like to "pick the collective brain" out there. I've put together a Google form (with a link to the resulting spreadsheet so everyone can see the contributions.) 


Suggest your fav iPad Apps for classroom use by going to http://t.co/q4bDG9C .

(You can view the spreadsheet as it's being populated here: http://bit.ly/gquHAz )

You can download the results as an excel and then sort it any way you want (by price, by subject, by name.)
